Question

the area of a circle is 154m².find the circumference of the circle

Answer 1

πr^2=154
r^2=154*7/22
r^2=49
r=7m
cicumference of circle =2πr
2*22/7*7=44m^2

Answer 2

area of the circle=154m sq
let the radius be r

therefore,
22/7*r2=154
r2=154*7/22
r2=49
r=√49
r=7
now,
the circumference of the circle =2*22/7*r
=2*22/7*7
=44m.
